Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional key or card systems are used, then physical access control is achieved, but the system requires manual code changes and physical key distribution which reduces convenience and security
Solution Approach 1:
The patent replaces mechanical key and card systems with a wireless mobile computing device system. The mobile device generates and transmits codes wirelessly to the door lock, eliminating the need for physical keys, cards, or manual code entry. This substitution of mechanical access methods with wireless electronic communication resolves the contradiction by improving convenience (no physical keys needed) while reducing management complexity (automatic code generation and distribution through the mobile application).
2Ease of operation
If manual code entry systems are used, then access control is achieved, but the system requires manual code changes which reduces ease of operation
Solution Approach 1:
The system performs preliminary action by pre-generating access codes through the mobile application before they are needed. The mobile device automatically creates and stores access codes in advance, eliminating the need for manual code changes at the time of access. This resolves the contradiction by making code entry extremely easy (simply present the mobile device) while eliminating the time loss associated with manual code changes.
Solution Approach 2:
The mobile application performs self-service by automatically generating, managing, and distributing access codes without requiring manual intervention. The system autonomously handles code creation, transmission to the door lock, and invalidation after use, eliminating the need for users to manually change codes or for administrators to manually update keypad systems. This resolves the contradiction by maximizing ease of operation while eliminating time consumption for code management.
3Reliability
If physical keys are distributed, then access is granted, but security is reduced due to key duplication and loss risks
Solution Approach 1:
The system uses digital code copying instead of physical key copying. The mobile application generates unique digital access codes that can be securely transmitted to multiple devices without the risks of physical key duplication. Each code is electronically created and can be instantly distributed or revoked, providing both high security (no physical duplication possible) and high convenience (instant digital distribution). This resolves the contradiction by maintaining strong security while greatly improving the ease of distributing access credentials.
Solution Approach 2:
The patent replaces the mechanical key distribution system with an electronic mobile device system. Instead of physically distributing keys that can be lost or duplicated, the system uses wireless transmission of generated codes to mobile devices. This substitution improves security by eliminating physical key vulnerabilities while enhancing convenience through automatic code generation and distribution via the mobile application.
4Reliability
If automatic locking is implemented, then security is improved, but the system complexity increases
Solution Approach 1:
The patent merges the code generation, transmission, and locking/unlocking functions into an integrated mobile device system. The mobile application combines multiple functions (code generation, wireless communication, timing control) into a single device that interacts with the door lock. This merging reduces overall system complexity compared to having separate systems for each function, while still providing automatic locking security. The integrated approach resolves the contradiction by achieving automatic locking security through a unified, manageable system rather than multiple complex separate components.

AI summary
A wireless door locking system is provided. The system includes a door lock having a locking device, a sensor and a microcontroller. The system also includes a mobile computing device having a display and a mobile application, wherein the mobile computing device is placed proximate to the door lock. The system includes a server in communication with the mobile computing device. The mobile application may generate a code such as a light pattern in response to communication with the server and transmits the light pattern from the display. The microcontroller of the door lock disengages the locking device in response to the sensor receiving the generated code communicated from the mobile computing device and determining that the generated code includes correct data to disengage the locking device of the door lock.
